Opinion article by Prof Johan Coetzee (MCBI, CMBE), Chairperson: Department of Economics and Finance, University of the Free State.

The Minister of Finance has not had it easy in 2025 and the budget speech not read yesterday pays testament to this. Postponing the speech to 12 March is unprecedented, and is due to the Government of National Unity (GNU) not reaching consensus on a way forward to tabling a budget. It seems as if the fallout was based largely on a proposed 2% increase to VAT that was rejected by two parties. I personally would not have supported this proposal either as the tax burden shifts disproportionally to the poor.

My initial response of the postponement was frustration and disappointment. But I soon realised that it is the outcome of a new government dispensation made up of many voices, and many dissenting at that, becoming more important. In principle, this is good for the nation, but unfortunate for us expecting the budget to be read on the day. It also does not necessarily send a good message to the markets, with the rand weakening by more than 1% within an hour of the announcement. There could also be knock-on effects that a later tabling will have on service delivery and operations of government. After some reflection, however, I have concluded that on balance, the decision to postpone is not as problematic as many have made it out to be over the past 24 hours. Clearly there are many balls to juggle by Minister Enoch Godongwana and many added complexities that have both national and international dimensions.

Lead-up to the budget

Internationally the strong nationalist policy drive by US President Donald Trump has already shown that the ‘make America great again’ mantra is alive and well as reflected in the intentional actions taken against South Africa since his second term started in January. We will see how this plays out over the coming months, but my view is that South Africa as a nation needs to be more deliberate in its policy agenda. We are at an inflection point where we must reflect on who we are as a nation and where we want to be down the line. We cannot afford to rely on handouts from other nations. There is more opportunity to this situation than threat, but we need intentional leadership to exploit it.

My big concern in the lead-up to the budget speech was that the minister would not take a firm stand on fighting the culture of non-compliance within state entities which has invariably led to unsustainable levels of irregular expenditure. For the 2023/24 financial year, the Auditor-General of South Africa reported that irregular expenditure totalled almost R50 billion, up from just over R27 billion the previous year. To put this into perspective, irregular expenditure equals approximately 2.2% of total government spending for the 2023/24 fiscal year. This might not seem significant stated as a percentage, but it has basically doubled since the previous year, and every preceding year before that too. Moreover, irregular expenditure equates to approximately 20% of the 2023/24 social grants budget and just about equals the 2024 National Student Financial Aid Scheme allocation. This is clearly a management failure and nothing seems to have been done about it over the years. As a result, the problem is escalating at an alarming rate. It is quite astounding that accountability management is not more explicit as it is clearly a very unpopular political message to send. But at what cost?

South African economy is not growing

To make matters worse, the South African economy is not growing both enough and fast enough. The most recent real GDP growth figure showed a decrease of 0.3% in the third quarter from the second quarter of 2024. Since 1994, the period with the highest annual rate of growth was a three-year period from 2005 to 2007 where growth exceeded 5% for each respective year. This period preceded the global financial crisis and since then, growth has struggled to reach 3% annually, doing so on only two occasions barring the 4.7% in 2021 which was not a true reflection of reality given the low base of the preceding year amid the COVID-19 pandemic. This is a major concern for the Minister, because with economic growth comes increased tax revenues, which in turn capacitates better budget management. Very simply, the more people spend; the more businesses sell; the larger the profit outcomes; the larger the tax revenue collections. If the economy grows, the fiscus collects more tax revenues without explicitly increasing tax rates. This built-in cyclical dynamic is simply not happening and creates a serious constraint on the ability of the Minister to manage deficits going forward.

Further to this of course is that as deficits are run, all things remaining constant, public debt increases. The public-debt-to-GDP ratio for 2023/24 already exceeds 72% which is higher than the generally accepted benchmark of 60% and almost 2.6 times what it was in 2008 (27.8%). This has resulted in the average interest on public debt approximating R1.1 billion a day, equating to about 22% of total tax revenues, or almost 20% of total government spending respectively. To put it differently, for every R1 government spends, 20 cents is first channelled to pay the interest on the debt before any spending occurs on roads, education, infrastructure, social grants and the like. These are deeply concerning figures in an economy with already high levels of unemployment and inequality.

Might be beginning of something better

There is a leadership void that cannot be ignored anymore. It needs to be intentional and deliberate. The GNU provides the platform to exploit ‘the best that South Africa has to offer’ as it promotes a broad-based and more inclusive political structure and played itself out yesterday. I welcome this in principle, but my concern is that political in-fighting will prevail and perverse politicking will trump working together in the best interests of the South African people. Although the postponement could be interpreted negatively in terms of the GNU not being able to find common ground, I think it is rather a sign of more rigorous engagement and the enablement of a collaborative environment amongst parties in the decision-making structures of the state. Remember this day as it might be the beginning of something better than what we are used to.

Nanotechnology breakthrough at UFS
2010-08-19

 Ph.D students, Chantel Swart and Ntsoaki Leeuw


Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil. 

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)  

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
